Yesterday I wrote about how difficult it is to tell different cell lines apart, including normal stem cells and cancer stem cells, especially since some accumulate accumulate oncogenic mutations that may make them seem more similar. A new paper is coming out that makes this case on a genomic level. Tomorrow’s Cell Stem Cell edition […]

What makes stem cells different? The stem cell field is faced with a dilemma as stem cells and some non-stem cells are sometimes too similar to tell apart. Even worse, stem cells and cancer cells are especially similar. If one focuses specifically on cancer stem cells (aka tumor initiating cells), the similarity between cancer stem

In this post I give my most interesting predictions about events in the stem cell field in 2011. Update: I’ve continuing doing predictions every year all the way through 2020 and intend to continue. See my 2012-2020 predictions here. Appeals court rules in favor of federally funded hESC research. This is more of a hope

My lab studies iPS cells. We are excited about iPS cells and they have enormous potential. However, there are some realities about iPS cells related to safety that impede our ability to use them to treat patients any time soon. We must solve these roadblocks before we can move forward, but interestingly, these facts are

Sheng Ding’s lab reports today in Cell Stem Cell (you can read it here) that they have replaced all genetic factors in a new iPS cell reprogramming method except Oct4. The other factors were replaced by chemical compounds. Thus, we continue a major transition in the iPS cell field away from genes and toward chemicals.

Cancer is a class of diseases that are intimately linked to stem cells. In fact, I would go so far as to call some types of cancer cells and stem cells, cousins. This concept, of a tight relationship between stem and cancer cells, is under intense investigation but at the same time it is something

The severe spinal cord injury sustained by Jockey Michael Martinez and the possibility (not realized) that he might be enrolled in Geron’s hESC-based spinal cord regenerative medicine trial, have drawn recent attention to spinal cord injury. Christopher and Dana Reeve (see foundation here) as well as Don C. Reed (see site here) were instrumental in bringing

In Lewis Carroll’s masterpiece, Alice in Wonderland, there is a wonderful passage that came to mind as I read the latest response from the self-proclaimed ‘adult stem cell researchers’ suing the government to stop federally-funded ES cell research: “I don’t know what you mean by ‘glory,’ ” Alice said. Humpty Dumpty smiled contemptuously. “Of course you

We live in a plastic world, full of BPA. Over the last 1/2 century, the proportion of our food and beverages that are consumed out of plastic containers has skyrocketed. Unfortunately, the concentrations of plastic-related chemicals in people around the world, even in remote corners, has gone up in parallel. I’ve written about avoiding plastic

Regenerative medicine is very exciting. But what’s even better than regenerative medicine? Preventative medicine. If one can prevent a problem for occurring in the first place, it is far better than trying to treat it after the fact. Of course in many cases we do not know the causes of diseases so it is difficult
